Supraphon has been the main record label for Czech music ever since 1932, and has been a major force in bringing Czech music to the rest of the world. Now as the world goes online for music so too goes Supraphon. On Thursday, its new online service, Supraphonline, will begin offering a part of the company’s massive archive of more than 100,000 recordings to internet buyers, in what was intended to be the first such service in the country. Christian Falvey talked to the record company’s business manager Antonín Milata.
